A Russian couple are facing trial after being accused of raping their own 12-year-old daughter. The married couple are accused of paedophilia after forcing their daughter to become their "sex slave".

The woman told investigators she had been raped as a 13-year-old. She and her husband agreed to "train their daughter in advance for adult life," she told police.

The ongoing abuse was discovered when the girl went to a doctor with "problems concerning her periods". Doctors then found that she was "not a virgin". She later told investigators she was being sexually abused.

The girl's parents allegedly confessed to the abuse they inflicted on her. They reportedly believed "it was better for the child to lose her virginity with her own father" than in any other way.
